Abstract: PURPOSE:To prevent deterioration of printing quality due to foam produced in ink during interruption of power source, by draining ink which has the possibility of containing foam from an ink feed path between an ink tank and an ink nozzle upon throw-in of power source, thereafter starting printing operation. CONSTITUTION:Upon throw-in of power source, an ink pressurizing pump 2 is operated to produce a proper pressure. Then an ink drainage valve 13 is opened followed by opening of an ink feed valve 1. Consequently, such ink as having the possibility of containing foam and the pressure thereof is recovered to normal level during power interruption is drained from an ink feed path between an ink feed valve 7 and an ink drainage valve 13 through an ink drainage tube 14 and recovered into an ink tank 25. The foam recovered into the ink tank together with the ink is separated naturally from the ink before it is pressurized again. Thereafter, the ink feed valve 7 and the ink drainage valve 13 are closed. When a cleaning water feeding device 16 is driven so as to clean the periphery of an orifice 11 of an ink nozzle 10 and the ink feed valve 7 is opened again, ink particles are ejected through the ink nozzle 10, thus enabling printing.

IPC: H04N5/44
Filed: 1994-09-28
Abstract: PURPOSE: To enable a viewer to easily view a television(TV) screen without being interrupted by a sampling line added to a 16:9 signal allowed to be viewed by the 4:3 screen of the TV by arranging the sampling line on the outside of a visible screen area. CONSTITUTION: A switch 55 in a voltage adding circuit 50 is opened when an aspect ratio is 4:3 and closed at the time of a 16:9 aspect ratio. At the time of 16:9 (the switch 55 is closed), a timing pulse is added to voltage appearing on a terminal 15 by the circuit 50. The lamp voltage of the TV is sufficiently boosted by a sampling line (useful image information) to be added to a TV signal. The sufficiently enough current is supplied to a vertical deflection coil and a signal is generated immediately before the arrangement of an image on the visual part of the TV screen. Since the 4:3 sampling line is generated just above the visible part of the screen, the sampling line is not viewed by a viewer, who is not interrupted by the line.
